Thermal Characteristics
Introduction
The temperature variable in Actel Designer software refers to the junction temperature, not the ambient, case, or
board temperatures. This is an important distinction because dynamic and static power consumption will cause the
chip's junction to be higher than the ambient, case, or board temperatures.
EQ 2-9
and
EQ 2-10
give the relationship
between thermal resistance, temperature gradient and power.
